Real-time context based recipe recommendation system

ABSTRACT

Aspects include real-time context based recipe recommendations including receiving, at a mobile device, an identifier of an available food item that is offered for purchase at a food marketplace. A request for recipes that specifies the identifier of the available food item and a list of identifiers of food items previously selected by the shopper for purchase is sent to a recipe application. At least one recipe selected by the recipe application is received at the mobile device and presented to the shopper. The recipe includes the available food item and at least a subset of the food times previously selected by the shopper. The identifier of the available food item is added to the list of food items previously selected by the shopper for purchase based on determining that the shopper has selected the available food item for purchase.

BACKGROUND

The invention relates generally to a recipe recommendation system, and more specifically, to a real-time context based recipe recommendation system.

One reason that shopping at a farmer's market is different than going to a grocery store is the changing variety of food item choices due, for example, to seasonal and other local conditions. Oftentimes shoppers do not bring a set grocery list but instead show up and see what looks good that week. Shoppers may find a unique food that they would like to try but aren't sure how to use or prepare the food. Thus, a shopper at a farmer's market runs the risk of buying a basket full of food and going home and still not having anything to make for meals because none of the purchased items work together. Coming home from grocery shopping with nothing to make for dinner may occur more frequently when shopping at a farmer's market type of venue however it can also happen when shopping in a standard grocery store when the store is out of a key ingredient, has seasonal specials, or has selected items at reduced prices.

SUMMARY

According to an embodiment a method, system, and computer program product for real-time context based recipe recommendation. A method includes receiving, at a mobile device of a shopper, an identifier of an available food item that is offered for purchase at a food marketplace. A request for recipes is sent by the mobile device to a recipe application, the request specifies the identifier of the available food item and a list of identifiers of food items previously selected by the shopper for purchase. At least one recipe selected by the recipe application is received at the mobile device, the at least one recipe including the available food item and at least a subset of the food items previously selected by the shopper for purchase. The shopper is presented with the at least one recipe. It is determined whether the shopper has selected the available food item for purchase. The identifier of the available food item is added to the list of identifiers of food items previously selected by the shopper for purchase based on determining that the shopper has selected the available food item for purchase.

DETAILED DESCRIPTION

Embodiments described herein are directed to providing real-time context based recipe recommendations. Embodiments can be used to provide suggestions on how to use new food ingredients by providing recipe suggestions that incorporate specified food ingredients in real-time (e.g., while the shopper is at a food marketplace such as a farmer's market or grocery store). Embodiments can also be used to help to optimize compatibility between the food items that a shopper is planning on purchasing by providing recipe suggestions that incorporate multiple items that the shopper has on hand (e.g., in the shopping cart, at home).

Existing radio-frequency identification (RFID) technology can be utilized by embodiments to track what is in a shopper's basket (i.e., previously selected) and what is available from a food vendor that is in front of (or proximate) to the shopper. As the shopper walks by a given ingredient, or food item, a shopping application on the shopper's mobile device presents the shopper (e.g., via a display screen) with recipes that include the given ingredient combined with other ingredients already in the shopper's basket. Recipe recommendations from the shopping application can also incorporate food items that the shopper has bought in the past. Recipes can be displayed on a mobile device such as, but not limited to: a Google Glass; a tablet; and a cellular telephone.

In embodiments, food items can be tagged with RFID tags which store identifiers of the food items. A mobile device used by the shopper can include a RFID reader to read the food item identifiers on the RFID tags. As the shopper moves around a food marketplace (e.g., a farmer's market or grocery store or other shopping venue), the items currently in front of the shopper can be compared to the food items that are already in the shopper's basket (food items previously selected by the shopper), and recipes involving the target item and some combination of items from the shopper's basket are suggested to the shopper. If past shopping habits of the shopper are available, they can be incorporated into a scoring algorithm to push things that the shopper is more likely to enjoy to the top of a list of recipes.

Turning now to FIG. 1, a block diagram of a system for a real-time context based recipe recommendation system is generally shown in accordance with an embodiment. The embodiment shown in FIG. 1 includes available food items 120 that are for sale by a vendor and selected food items 108 that are in the shopper's basket (food items previously selected by the shopper). Both the available food items 120 and the selected food items 108 include RFID tags 110 that are read by a RFID reader 122 located on a mobile device 102. In an embodiment, the RFID tags 110 store identifiers of the corresponding food item that can be read by the RFID reader 122 as input to the shopping application 104. In embodiments, the RFID tags 110 are passive in that they collect energy from the interrogating radio waves and act as passive transponders to return the food item identifiers to the RFID reader 122. The RFID reader 122 sends an encoded radio signal to interrogate a RFID tag 110, which responds with a tag identifier. In embodiments, the tag identifier is translated by the shopping application 104 into a food item identifier, in other embodiments, the RFID tags 110 return food item identifiers along with tag identifiers to the RFID reader.

The shopping application 104 receives the food item identifiers for the available food items 120 and the previously selected food items 108. In an embodiment, the shopping application 104 requests updates on contents of the shopping cart, e.g., the previously selected food items 108 on a periodic basis. The RFID reader 122 can distinguish between signals received from the available food items 120 and already selected food items 108 in a variety of manners such as, but not limited to: scanning or otherwise directly recording selected items as they are placed in the cart rather than relying on the RFID as a proximity sensor. In other embodiments, RFID technology is combined with movement sensors on the food items and the algorithm can see the difference between items that are moving in conjunction with the shopper and those that remain at a consistent distance (e.g., a programmable threshold distance) from the shopper vs. other items that are changing their distance as the shopper moves around.

The food item identifiers for the available food items 120 and the selected food items 108 can be transmitted, as shown in FIG. 1 via a network 112, by the shopping application 104 to a recipe application 116 for recipe suggestions. In embodiments, information 106 such as items on hand in the shoppers home and preferences of the shopper are also sent to the recipe application 116. The recipe application 116 is shown in FIG. 1 as being implemented on a processor 114 and having access to recipe data 118 stored in a storage device. Any recipe application 116 that can receive recipe ingredients as input and that can output a suggested recipe(s) based on the ingredients can be utilized by embodiments. For example, Supercook, Recipes By Ingredients from AB Mobile Apps, and MyFridgeFood are examples of a few of the recipe applications 116 that can be utilized by embodiments. In addition, a recipe application 116 that generates new recipes based on ingredients, such as that described in U.S. Patent Publication Number 2014/0188566, can also be utilized by embodiments. The recipe application 116 can be located and executed on a processor 114 remote from the mobile device 102 as shown in FIG. 1. Alternatively, all or a portion of the recipe application 116 and its associated recipe data 118 can be located on the mobile device 102. Similarly, the shopping application 104 can be located and executed on the mobile device 102 as shown in FIG. 1. Alternatively, all or a portion of the shopping application 104 and associated information 106 can be located on the processor 114 remote from the mobile device 102.

Turning now to FIG. 2, a process flow for real-time context based recipe recommendation is generally shown in accordance with an embodiment. In an embodiment, the processing shown in FIG. 2 is performed by the shopping application 104 executing on the mobile device 102 shown in FIG. 1. In embodiments, the shopping application 104 is initiated, which causes the RFID reader 122 on the mobile device 102 to send radio signals to interrogate RFID tags 110 which are proximate (within reception range of the radio signals) to the mobile device 102. At block 202, a shopper walks past a food item that is tagged with an RFID tag 110. At block 204, the shopping application 104 receives the tag identifier (and optionally other information) from the RFID reader 122 and identifies the available food item(s) 120.

At block 206, the shopping application 104 sends the identifier of the available food item 120 along with identifiers of any selected food items 108 that are already in the shopper's basket (or cart, or otherwise in possession of the shopper) to the recipe application 116. In this manner, the shopping application 104 sends a list of ingredients to the recipe application 116 and requests recipe suggestions. In embodiments, the shopping application 104 sends additional information to the recipe application 116 related to shopper preferences which can be factored in by the recipe application 116 when selecting recipes and/or by the shopping application 104 when presenting recipes to the shopper. Preferences can relate to, but are not limited to: foods to avoid (e.g., due to allergies, dislikes, dietary restrictions); favorite foods; preferred spice level; length of time to cook; length of time to prepare; and preferred cooking methods.

In embodiments, the shopper can receive, via a display on the mobile device 102, a list of available food items 120 and the shopper can select one or more of the available food items 120 for inclusion in a recipe. In these embodiments, just the selected available food item (s) 120 is sent to the recipe application 116. Similarly, the shopper can indicate a subset of the selected food items 108 in the shopper's basket for inclusion in a recipe, with only the indicated subset sent to the recipe application 116 for recipe suggestions.

At block 208 of FIG. 2, the shopping application 104 receives one or more suggested recipes back from the recipe application 116 that uses the available food item(s) 120 and possibly one or more additional ingredients that the shopper has already selected for purchase. The one or more suggested recipes are presented to the shopper for example, via a display on the mobile device 102 or in an audible fashion via a speaker on the mobile device 102. In embodiments, the suggested recipes are ranked based on what percentage of the previously selected food items 108 are used by the recipe. In embodiments, additional on hand food items, such as those at the shopper's home are also taken into account by the ranking.

At block 210 of FIG. 2, it is determined whether the shopper has placed one of the available food items 120 in his or her basket. If the available food item 120 was placed in the shopper's basket, then block 212 is performed to indicate that the available food item 120 is now a selected food item 108 (e.g., is on list of food items previously selected by the shopper). If the available food item 120 was not placed in the shopper's basket, then processing continues at block 202 where the shopper continues to walk past food items which are monitored by the shopping application 104.

Turning now to FIG. 3, a process flow for real-time context based shopping recommendation is generally shown in accordance with an embodiment. In an embodiment, the processing shown in FIG. 3 is performed by the shopping application 104 executing on the mobile device 102 shown in FIG. 1 once the shopper is presented with a list of one or more recipes that were received from the recipe application 116 (e.g., at block 208 of FIG. 2). At block 302 of FIG. 3, the shopper selects a recipe from the list of recipes and at block 304 of FIG. 3, the shopping application 104 checks to see what ingredients in the recipe that the shopper has on hand. In an embodiment, the ingredients that are on hand are the food items that the shopper has in his or her shopping cart. In other embodiments, the ingredients that are on hand also include the food items that the shopper has at home (or other location). The food items at home can be determined by the shopping application 104 using the RFID reader and/or they can be entered manually by the shopper.

At block 306 of FIG. 3, the shopping application 104 presents the shopper with a list of at least one additional ingredient that is needed for the selected recipe. In an embodiment, this list includes those food items that are not in the shopper's cart. In other embodiments, the list includes those food items are not in the shopper's cart and not at the shopper's home. The list of at least one additional ingredient can be presented to the shopper for example, via a display on the mobile device 102 or in an audible fashion via a speaker on the mobile device 102. In another embodiment, instead of showing the exact ingredients from the selected recipe, the shopping application 104 can show categories of ingredients (e.g., root vegetables, leaf vegetables, red meat) and notify the shoppers whenever they walk by one or more ingredients in those categories. At block 308, the shopping application 104 continues to update the list of additional ingredients required by monitoring the food items that the shopper puts in his or her basket. It is determined at block 310 whether the shopper has all of the ingredients for the selected recipe. Block 312 is performed and the recipe is marked as complete when it is determined at block 310 that the shopper has all of the ingredients for the selected recipe. Processing continues at block 306 based on the shopping application 104 determining at block 310 that the shopper does not have all of the ingredients for the selected recipe at block 310. In embodiments, the processing shown in FIG. 3 is performed simultaneously for two or more recipes that are selected by the shopper.

Turning now to FIG. 4, a process flow for real-time context based menu planning is generally shown in accordance with an embodiment. In an embodiment, the processing shown in FIG. 4 is performed by the shopping application 104 executing on the mobile device 102 shown in FIG. 1. In an embodiment, the processing shown in FIG. 4 supplements the processing shown in FIGS. 2 and 3. For example, block 402 can be performed prior to the processing shown in FIG. 2 and FIG. 3. At block 402, a shopper enters a menu plan that includes categories of meals into the shopping application. In an embodiment, a shopper can enter the menu plan prior to shopping to generally define types of meals for particular days and times. Categories can be focused on types of food, such as hamburger for dinner on Monday, fish on Tuesday, meatless on Wednesday, and pasta on Thursday. Categories can also be focused on types of meals, such as, but not limited to: the amount of time that it takes to prepare, the amount of time that it takes to cook, the type of cooking (e.g., pan, oven, outdoor grill), the total number of different ingredients, and level of cooking skill suggested. Categories can be combined, for example, a recipe for fish that takes less than an hour to prepare and that also can be prepared on an outdoor grill can be specified for a meal. The shopping application 104 requests a recipe from the recipe application 116 fitting as many categories as possible. Recipes can be ranked for presentation to the shopper based on how many categories they match.

At block 404 of FIG. 4, the shopper is presented (e.g., via a display or audio output on mobile device 102) with recipes in one of the categories that is not completed. In embodiments, block 404 is performed as part of block 208 of FIG. 2. At block 404, the shopper is presented with recipes in one of the categories of meals that is not completed. For example, if the shopper requests a recipe that includes grilling fish on an outdoor grill and a recipe is returned from the recipe application 116 that fits these categories, and selected by the shopper at block 406, then this meal category is marked as complete at block 408. Thus, at block 208 in FIG. 2, the shopper is no longer presented with recipes that fall into this meal category. Processing continues at block 410, where it is determined whether all of the meal categories have been completed. If they have not been completed, then processing continues at block 404.

In an embodiment, a shopper enters a menu plan that includes: chicken cooked on a grill on Monday; a vegetarian meal on Tuesday; and a pasta meal with hamburger on Wednesday. When the shopper is walking around the farmer's market, the shopper may have fresh dill in his or her basket, and be passing by fresh lemons. The shopping application 104 can request recipes that include dill and lemons; as well as one of chicken cooked on a grill; a vegetarian meal; and a pasta meal with hamburger from the recipe application 116. The shopper can be presented with a list of recipes including a dill and lemon marinade sauce for grilled chicken, as well as a vegetarian casserole with dill and lemon. The shopper can select the recipe for the dill and lemon marinade sauce for grilled chicken. The shopping application 104 can then track the required ingredients for the recipe as described in reference to FIG. 3. In addition, the shopping application will no longer present recipes for chicken cooked on a grill to the shopper during this shopping trip since that category has been complete. Instead, at block 404, the shopping application 104 can request recipes that include a vegetarian meal or a pasta meal with hamburger from the recipe application 116. In this manner, a shopper can fill out an outline of a menu plan and make final decisions based on what food items are available.

In an embodiment, food items required by selected recipes that are not in the shopper's cart or the shopper's home can be presented, or output, to the shopper via a display on the mobile device 102 or to a printer. In embodiments, the remaining items can be sent automatically to a grocery ordering service for delivery to the shopper.

Embodiments can be implemented with any technology that allows for a food item to be recognized by an application executing on a mobile device. For example, in embodiments, image recognition, barcodes and/or quick response (QR) code scanners can be used in place of or along with RFID for identifying food items.

Turning now to FIG. 5, a block diagram of a computing device for implementing some or all aspects of the system is generally shown in accordance with an embodiment. FIG. 5 illustrates a block diagram of a computing device 500 for use in implementing a system or method according to some embodiments. The systems and methods described herein may be implemented in hardware, software (e.g., firmware), or a combination thereof. In some embodiments, the methods described may be implemented, at least in part, in hardware and may be part of the microprocessor of a special or general-purpose computing device 500, such as a cellular phone, a personal digital assistant (PDA), tablet computer, personal computer, workstation, minicomputer, or mainframe computer for example.

In some embodiments, as shown in FIG. 5, the computing device 500 includes a processor 505, memory 510 coupled to a memory controller 515, and one or more input devices 545, and output devices 540, which are communicatively coupled via a local I/O controller 535. These devices 540, 545 may include, for example, a printer, a scanner, a microphone, and the like.

Systems and methods according to this disclosure may be embodied, in whole or in part, in computer program products or in computing device 500, such as that illustrated in FIG. 5.

It is understood in advance that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.

Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.

Characteristics are as follows:

-   -   On-demand self-service: a cloud consumer can unilaterally         provision computing capabilities, such as server time and         network storage, as needed automatically without requiring human         interaction with the service's provider.     -   Broad network access: capabilities are available over a network         and accessed through standard mechanisms that promote use by         heterogeneous thin or thick client platforms (e.g., mobile         phones, laptops, and PDAs).     -   Resource pooling: the provider's computing resources are pooled         to serve multiple consumers using a multi-tenant model, with         different physical and virtual resources dynamically assigned         and reassigned according to demand. There is a sense of location         independence in that the consumer generally has no control or         knowledge over the exact location of the provided resources but         may be able to specify location at a higher level of abstraction         (e.g., country, state, or datacenter).     -   Rapid elasticity: capabilities can be rapidly and elastically         provisioned, in some cases automatically, to quickly scale out         and rapidly released to quickly scale in. To the consumer, the         capabilities available for provisioning often appear to be         unlimited and can be purchased in any quantity at any time.     -   Measured service: cloud systems automatically control and         optimize resource use by leveraging a metering capability at         some level of abstraction appropriate to the type of service         (e.g., storage, processing, bandwidth, and active user         accounts). Resource usage can be monitored, controlled, and         reported providing transparency for both the provider and         consumer of the utilized service.

Service Models are as follows:

-   -   Software as a Service (SaaS): the capability provided to the         consumer is to use the provider's applications running on a         cloud infrastructure. The applications are accessible from         various client devices through a thin client interface such as a         web browser (e.g., web-based e-mail). The consumer does not         manage or control the underlying cloud infrastructure including         network, servers, operating systems, storage, or even individual         application capabilities, with the possible exception of limited         user-specific application configuration settings.     -   Platform as a Service (PaaS): the capability provided to the         consumer is to deploy onto the cloud infrastructure         consumer-created or acquired applications created using         programming languages and tools supported by the provider. The         consumer does not manage or control the underlying cloud         infrastructure including networks, servers, operating systems,         or storage, but has control over the deployed applications and         possibly application hosting environment configurations.     -   Infrastructure as a Service (IaaS): the capability provided to         the consumer is to provision processing, storage, networks, and         other fundamental computing resources where the consumer is able         to deploy and run arbitrary software, which can include         operating systems and applications. The consumer does not manage         or control the underlying cloud infrastructure but has control         over operating systems, storage, deployed applications, and         possibly limited control of select networking components (e.g.,         host firewalls).

Deployment Models are as follows:

-   -   Private cloud: the cloud infrastructure is operated solely for         an organization. It may be managed by the organization or a         third party and may exist on-premises or off-premises.     -   Community cloud: the cloud infrastructure is shared by several         organizations and supports a specific community that has shared         concerns (e.g., mission, security requirements, policy, and         compliance considerations). It may be managed by the         organizations or a third party and may exist on-premises or         off-premises.     -   Public cloud: the cloud infrastructure is made available to the         general public or a large industry group and is owned by an         organization selling cloud services.     -   Hybrid cloud: the cloud infrastructure is a composition of two         or more clouds (private, community, or public) that remain         unique entities but are bound together by standardized or         proprietary technology that enables data and application         portability (e.g., cloud bursting for load-balancing between         clouds).

A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure comprising a network of interconnected nodes.

Referring now to FIG. 6, illustrative cloud computing environment 350 is depicted. As shown, cloud computing environment 350 comprises one or more cloud computing nodes 352 with which local computing devices used by cloud consumers, such as, for example, personal digital assistant (PDA) or cellular telephone 354A, desktop computer 354B, laptop computer 354C, and/or automobile computer system 354N may communicate. Nodes 352 may communicate with one another. They may be grouped (not shown) physically or virtually, in one or more networks, such as Private, Community, Public, or Hybrid clouds as described hereinabove, or a combination thereof. This allows cloud computing environment 350 to offer infrastructure, platforms and/or software as services for which a cloud consumer does not need to maintain resources on a local computing device. It is understood that the types of computing devices 354A-N shown in FIG. 6 are intended to be illustrative only and that computing nodes 352 and cloud computing environment 350 can communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser).

Referring now to FIG. 7, a set of functional abstraction layers provided by cloud computing environment 350 (FIG. 6) is shown. It should be understood in advance that the components, layers, and functions shown in FIG. 7 are intended to be illustrative only and embodiments of the invention are not limited thereto.
